"If you always do what you always did, you will always get what you always got."
("Moms" Mabley)

- Without trying something new, then there will be no change in the result. You need to try other new things in order to get a different result. If one hesitates to try something new out of fear, then one would not learn new materials and would not be able to discover something new. Try new things, and do not hesitate out of fear for there is something worth that much of the risk.

"Man will occasionally stumble over the truth, but most of the time he will pick himself up and continue on."
(Winston Churchill)

- Sometimes truth is harsh and bring great disaster but one will be able to over come and accept the truth, no matter how harsh or great disaster it brings to oneself or the world. The Scientific Revolution was a great shock to the people but today, people accept it and live with it. No matter how shocking the truth is or how one denies it, truth is truth and there is no way to get out of it or get rid of it because truth cannot be destroyed. One must bear with it because once one bears with it, one can over come it and will be able to continue one's life without a problem.

"Always tell the truth. That way, you don't have to remember what you said."
(Mark Twain)
- When one is telling a lie, then one needs to continuously remember what one said to others to not be caught but when one tells the truth every single time, then one does not need to worry because whatever one said to another is the truth and therefore no troubles will be brought to oneself. When one tells a lie, the number of lies continuously increases to cover up the lie, therefore one needs to remember all the words one said. When one tells the truth, however, one does not need to remember what one said because it is true and it can be confirmed by others as well and one does not need to worry about what one said to another.
